The difference between zirconia ball and zirconia silicate ball

According to the zirconium content, zirconia beads can be divided into 95 pure zirconium beads, zirconium aluminum composite beads, zirconium silicate beads, cerium zirconium beads, because of the different composition, the specific gravity will be different, the color will be very different.

Under normal circumstances, the zirconia beads are yttrium stabilized zirconia beads, containing about 94.6% zirconia, containing about 5.2% yttrium oxide, 95 zirconia beads, pure white color, wear resistance and strength are very good, Mohs hardness can reach level 9. The bead size can be 0.03mm-50mm.

Zirconium silicate beads, zirconium content about 65%, silica about 35%, the color is not pure white, yellow or red, Mohs hardness is generally about 7.2, Vickers hardness of more than 900, its wear resistance is not as good as 95 pure zirconium beads, but its price is affordable. It is widely used in coating, paint and suspension agent industry.
